Can b going down the rd and vehicle will die. Put in neutral and coast and will restart. Occasionally will have to pull off rd and sit for a min and it will restart. In warm weather it does it a lot. In cold weather it hardly does it at all. Have changed fuel filter. Also have had it hooked up to a machine and it shows nothing wrong. U can also b going down rd and floor it and it will not accelerate at all and will coast then die. Thinking fuel pump but no clue.

Usually, a fuel pump will sputter a bit before there is a complete engine stop. I've had lots of fuel pumps fail, but usually, it's a no start.
I real fast engine stop is likely an electrical problem, does it act like someone just turned off the key?

Yes it's just like u simply turn key off. Also occasionally when u start vehicle it won't start, like out of gas but if u turn key and let it sit in the on position for few seconds then turn to start it will start with no hesitation.
